Assassination of Franz Ferdinand
Ferdinand was the crown prince of the Austrian empire.
In 1914 he and his wife went on a visit to Serbia,
a country that Austria had a strong influence over.
Several Serbian nationalists, who wanted independence
from Austria, decided that they would try to kill
the prince. On 28th June 1914 they succeeded.
His death led to the Austrian government making
very strong demands on Serbia. Russia, keen to gain
influence in Serbia, supported the Serbs. Days later
the First World War had begun with the Germans declaring
war on Russia.
